INSTALLATION

Connecting Cables

When dual FCH is provided for the HUB dedicated to each internal LANI card (LANI-A: in Slot 00 of each CPR), connect FCH#0 to HUB#0 and FCH#1 to HUB#1.

When your system also uses the external LANI cards (LANI-B in Slot 03 of each CPR), prepare another set of FCH cards for the HUB dedicated to the external LANI cards. Then, if the FCH is in dual configuration, connect one FCH to the HUB for No. 0 system of the external LANI, and the other to the HUB for the No. 1 system of the external LANI.

Figure 4-12shows an example of a HUB in a dual configuration and the FCH card mounted in PIM 1 of the 1 IMG system.

This figure shows an example where HUB is provided in a dual configuration and FCH card is mounted in PIM1 of 1-IMG system.
